von Braun Cyanogen Bromide Reaction, Solasodine, 13C NMR Solasodine on reaction with BrCN yielded two isomeric cyanamides in a ratio of 3:1, which have been characterised as C-22 configurational isomers, N-cyanosolasodine (22 R, 25 R) I IA and N-cyanosolasodine (22 S, 25 Rj II B on the basis of HI and *3C NMR studies. The same reaction with piperidine, yielded its cyanamide, the 13C NMR of whic...
